SUMMARY:Forty Years of Change in a Serpentine Grassland, a talk by Lauren Hallett
LOCATION: Zoom registration: www.cnps-scv.org/npls-20240208
DESCRIPTION:\nZoom registration: https://us02web.zoom.us/meeting/register/tZwuce2spz4qE
 tJfI-9iP1_BVneCmErf0Vdw (https://us02web.zoom.us/meeting/register/tZwuce2sp
 z4qEtJfI-9iP1_BVneCmErf0Vdw)\nSerpentine grasslands support a relatively hi
 gh proportion of California’ endemic plant diversity, providing a colorful 
 display every spring. Which species – and which colors – we see every year 
 are highly variable. Here Professor Hallett shares findings from 40+ years 
 of annually observing species composition in a serpentine grassland at Jasp
 er Ridge Biological Preserve ‘Ootchamin ‘Ooyakma. She describes how gopher 
 disturbance and climate variability generating a shifting mosaic of species
  abundances over space and time. While serpentine grasslands have largely r
 esisted invasion by non-native grasses due to their harsh soil conditions, 
 she outlines how atmospheric nitrogen deposition, especially in conjunction
  with high rainfall years, can facilitate invasion into the system. She wil
 l close with a discussion of management options to maintain serpentine plan
 t diversity into the future.\nLauren Hallett is an associate professor in t
 he Biology Department and Environmental Studies Program at the University o
 f Oregon. Her lab aims to produce “usable” science to improve ecosystems.\n
